The docker compose CLI utility allows users to run commands on multiple containers at once; for example, building images, scaling containers, running containers that were stopped, and more. [30] Commands related to image manipulation, or user-interactive options, are not relevant in Docker Compose because they address one container. [31] The ...
Individually, each container simulates a different software application and runs isolated processes [4] by bundling related configuration files, libraries and dependencies. [5] But, collectively, multiple containers share a common operating system kernel (OS). [6]
cgroups (abbreviated from control groups) is a Linux kernel feature that limits, accounts for, and isolates the resource usage (CPU, memory, disk I/O, etc. [1]) of a collection of processes. Engineers at Google started the work on this feature in 2006 under the name "process containers". [2]
systemd tracks processes using the Linux kernel's cgroups subsystem instead of using process identifiers (PIDs); thus, daemons cannot "escape" systemd, not even by double-forking. systemd not only uses cgroups, but also augments them with systemd-nspawn and machinectl , two utility programs that facilitate the creation and management of Linux ...
Unraid utilizes Docker to allow users to create and manage Docker containers to host applications on the system. In doing so, this allows Unraid users to host applications that may not support the Unraid operating system directly, could be difficult to install & remove, or may not behave correctly with other applications running on the same system.

pstree is a Linux command that shows the running processes as a tree. [1] [2] [3] It is used as a more visual alternative to the ps command. The root of the tree is either init or the process with the given pid. It can also be installed in other Unix systems. In BSD systems, a similar output is created using ps -d, in Linux ps axjf [4] produces ...
A grid computing system that connects many personal computers over the Internet via inter-process network communication. In computer science, interprocess communication (IPC) is the sharing of data between running processes in a computer system. Mechanisms for IPC may be provided by an operating system.
